一、前言 低速旋转设备通常大多数是大型、重要设备。由于设备的突发故障而停机,给工厂造成的停工损失很大。 此外,因为是大型设备,轴承所承受的负载也大。轴承使用到损坏时,机器损伤的部位不仅限于轴承本身,而其它零件,如主轴的损伤、变形和破损,以及由于破片的落入以致损坏齿轮,这种造成二次损伤的情况也不少。 我们旭化成公司也不例外。在石油化学工厂中,溶融状态的聚合物搅拌机、挤压机或者树脂车间和纤 I. Introduction Low-speed rotating equipment is usually the majority of large, important equipment. Shutdowns due to sudden equipment failure caused significant downtime losses to the plant. In addition, because it is a large equipment, bearing the load is also large. Damage to the bearings, the damage to the machine parts are not limited to the bearings themselves, while other parts such as the spindle damage, deformation and damage, as well as the fragments fall into the gear and thus damage the gear, causing secondary damage in many cases. Asahi Kasei Corporation is no exception. In petrochemical plants, molten polymer mixers, extruders or resin workshops and fiber
